md/r5cache: sysfs entry journal_mode With write cache, journal_mode is the knob to switch between write-back and write-through. Below is an example: root@virt-test:~/# cat /sys/block/md0/md/journal_mode [write-through] write-back root@virt-test:~/# echo write-back > /sys/block/md0/md/journal_mode root@virt-test:~/# cat /sys/block/md0/md/journal_mode write-through [write-back] Signed-off-by: Song Liu <songliubraving@fb.com> Signed-off-by: Shaohua Li <shli@fb.com>
